Another way to say this is that the upper right corner of A *could* be
part of the class space, if there were any references to those
packages from within the shaded class space... i.e., it's not blocked
or incompatible.
It just happens that there are no references to it from the class
space so it doesn't need to be included. This is the only difference
between the upper right and lower right parts of A. The diagram is not
sufficiently clear on this point.

A class space is basically a namespace where every name is uniquely mapped to a single source. The class spaces are defined by the uses constraints. We never sat down for a good definition so it is not as crisp as I like it to be but the unshaded part can actually be in another class space, maybe to clarify this we need to say "a Class Space for Bundle A".
